The Great Underground Empire 

In The Great Underground Empire you are near a great underground 
labyrinth, which is reputed to contain vast quantities of treasure. No doubt, 
you wish to acquire some of it. In order to receive full credit for treasure, you 
must deposit it safely in the trophy case. 

In addition to treasure, the labyrinth contains various objects that may or may 
not be useful in your attempt to acquire the treasure. You may need sources of 
light, since caves are often dark, and weapons, since dungeons often have 
unfriendly beings wandering about in them. Reading material is scattered 
around as well, and you might even find some of it useful. 

Beware of the thief! He is a dastardly anti-social type and a skilled 
pickpocket. Watch out for your valuable possessions when he is near. 

To measure your success, ZORK keeps track of your score. You receive points 
for finding treasure, for securing it in the trophy case, for performing certain 
actions, and for visiting certain places. There is a penalty for getting yourself 
killed. 

In this story, time passes only in response to your input. You might imagine a 
giant clock that ticks once per move and the story progresses only at each tick. 
Nothing happens in the story while you are thinking and planning your next 
move, so you can plan your moves slowly and carefully if you so choose. 

The line displayed at the top of your screen tells you the room you are in. your 
current score and how many moves it took you to achieve this: 

= 00M: SCORE: MOVES: 

Concepts for Exploring 

Some things that you can do with objects in this story are not immediately 
obvious. 

Containment: Some objects can contain other objects. Some containers can be 
opened or closed, and some are always open. Some are transparent, and some are 
not. Most containers have a limited capacity, and all objects have sizes, so that 
it is possible to fill up containers. Similarly, some objects have surfaces on which 
other objects can be placed. 

Fighting: Characters in the story will, as a rule, fight back when attacked. They 
may. in some cases, attack you unprovoked. Some of these beings are stronger 
than others: it might be advisable to wait a while before taking them on. 



Rules and Strategies 



Emerging second-best in a fight may leave you somewhat the worse for wear: 
you might want to ask ZORK to diagnose your condition isee Appendix B. 
"Command Summary"). 

Vehicles: There are objects in the story that have the ability to transport the 
fearless player to mysterious regions that are inaccessible on foot. Needless to 
say, one faces great personal peril in venturing into such regions. 

Directions: The passages connecting rooms in The Great Underground Empire 
sometimes twist and turn unpredictably. You cannot expect that after going 
north, you can always return to where you were by going south. 

Talking to ZORK 

When you play a ZORK game, you talk to ZORK in plain English, by typing in 
all your requests on your computer's keyboard when you see the prompt IX. 
(ZORK allows you to abbreviate some words because you use them often.) When 
you have finished typing a line, press the ENTER | key and ZORK will consider 
your request. 

ZORK usually acts as though your sentence begins with "I want to ...". 
although you should not type these exact words. ZORK then displays a response 
that tells you whether what you want to do is possible in the current situation, 
and. if it is. whether anything interesting happens as a resuit. 

All words you type are distinguished by their first six letters and all subsequent 
letters are ignored. For example, typing Open the encyclopedia is equivalent to 
typing Open the encyd or better still. Open the book. ZORK doesn't care 
whether you type in capital letters or lower case letters, or a mixture. 

ZORK understands many different types of sentences. A sentence must contain 
a verb and usually an object. Some examples: 

Take the gold. Drop goid. Pick up gold. Put down the goid. Go north. North. 
Walk north. N. Push burton. Push the red button. Open wooden door. Look at 
the wall. Look under rock. Look behind curtain. Look in bag. Read a book. Read 
all of the books. Drop all. Take all. Drop all but the knife. 

You must separate multiple objects of a verb by the word "and" or a comma (.). 

Take all but the knife and the lamp. Put the gold and jeweis in the trophy case. 
Throw the newspaper, the red book, and the magazine in the chasm. 

You can include several sentences in one input line if you separate them by the 
word then or a period. You don't need to type a period at the end of an input 
line. For example: 



J 11 



Rules and Strategies 



Take book. N. Drop book and candle. 

Take the book then N. Drop book and candle 

There are only two kinds of questions that ZORK understands: What and 
Where. For example: 

Where Is the gold? What is a grue? 

ZORK tnes to be clever about what you really mean when you don't give enough 
information. If you say that you want to do something, but you don't say what 
to do it with or to, ZORK will sometimes decide that there was only one possible 
object you could have meant. When it does decide, it will tell you. by displaying, 
for example, with the r cce'. If your sentence is really ambiguous. ZORK will 
ask you what you really meant. ZORK may ask. for example. With wnat-; this 
can be answered briefly, by typing iT" "o~ "p* ~e~. 

In a way. ZORK's vocabulary is lopsided, because ZORK uses many more words 
than it understands. ZORK's vocabulary consists of several hundred words, and 
includes neariy all the words that you are likely to use in conversing with ZORK. 
However. ZORK's responses may be quite elaborate at times, and ZORK will 
display English descriptions that it couldn't possibly analyze. Indeed. ZORK's 
response may refer to something to which you cannot refer iperhaps to your 
d ism ay). In that case, it is not essential to the story, and appears in ZORK's 
responses only to enhance your mental imagery. 

Completely mystifying sentences will cause ZORK to complain in one way or 
another, and. after making the complaint- ZORK will ignore the rest of the input 
line. Unusual events, such as being attacked, will also make ZORK ignore the 
rest of the sentences you typed, since the event may have changed your situation 
drastically. 

ZORK's Pedagogy 

ZORK may occasionally have a few words for you when it wants you to clarify 
an instruction you've given. Some of ZORK's remarks are: 

! con": <-:w the wore ' .C'jr word)'.— The word you typed is not in the game's 
vocabulary. Sometimes a synonym or rephrasing will be understood. If not, 
ZORK probably doesn't know the idea you were trying to get across. 

i can't .je the worrj ' .cjr word)' he r e — ZORK knows the word you typed. 
but the word made no sense where you put it in the sentence: Open the take, for 
exampJe, 

V CJ ~ _5t s^oply 3 \ e' c — Unless you are answering a question, each sentence 
must Lave a verb (or a command) in it somewhere. 



12 



Rules and Strategies 



There is a r.oun miss.ng n ~-a: sentence —This usually indicates an incomplete 
sentence, such as Put the lamp in the . where ZORK expected another noun and 
couldn't find one . 

Too many noun clauses —An example is: Put the troll in the basket with the 
shovel. A legal sentence has. at most, one direct object and one indirect object. 

Beg parccn?— You did not type anything after the prompt ( > ) or before you 
pressed the ENTER key on your keyboard. 

It's too dark to see.— In the story, there was no light to see objects in the room. 

i cannot see anv <ob;ec:> ^e'e. — In the story, the object you referred to was not 
accessible to you. 

Multiple CD.ects canned ce usea with >',c-' .era).— It is valid for you to use 
multiple objects (that is. nouns or noun phrases separated by "and" or a comma) 
only with certain verbs. Among the more useful of these verbs are take. drop. 
and put. 

I don't Lnce r s:ana tra: se-te-re.— You typed a sentence that is gibberish to 
ZORK. for example. Give trofl with sword. You might try rephrasing the 
sentence. 

Commands for Exploring 

The best way to move from place to place is to type the direction you want to 
go. Acceptable directions are North or X. South or S, East or E. West or W. XE 
for Northeast or NW, SE. SW ifor Northwest. Southeast or Southwest respec- 
tively), U or Up. and D or Down. 

When you enter a particular place (ZORK cails any kind of a place a "room") for 
the first time. ZORK usually displays the name of the room, a description of it. 
and then descriptions of any interesting objects in the room with which you 
might want to interact. When you return to a room, ZORK normally displays 
just the name of the room and the names of the objects in it. The VERBOSE 
command tells ZORK to give the description of rooms and objects every time 
you go there, not just the first rime. The BRIEF command tells ZORK to 
describe fully only newly encountered rooms and objects. For moving through 
areas you already know well, the SUPERBRIEF command tells ZORK to give 
only the name of a room leven on your first visit there), and not even to mention 
objects in the room. You can aiways get a description of the room you are in and 
the objects in it by typing _L_ _0_ _Oj JCj (or the abbreviation L). 

Hint: Exploring The Great Underground Empire will be much easier if you make 
a map as you move around.

List of ZORK Commands 

To amp lify your adventuring, you may order ZORK to give you information by 
typing specific commands. These commands can be used over and over again as 
needed, but they are each considered one complete move. 

The list of commands is: 



AGAIN 



BRIEF 



DIAGNOSE 



INVENTORY 



LOOK 



QUIT 



RESTART 



RESTORE 



SAVE 



SCORE 



ZORK will respond as if you had repeated your previous 
sentence. 

This commands ZORK to fully describe only newly 
encountered rooms and objects. Rooms already visited and 
objects already seen will be described by printing the room 
name and the object names only. 

ZORK gives you a medical report of your physical condition. 
This is particularly useful if you have just survived a 
dangerous battle. 

ZORK lists your possessions. If you've noticed the thief 
lurking about, you might want to check to see if your 
belongings are still there. You may abbreviate 
INVENTORY by typing I. 

ZORK describes your surroundings in detail. You may 
abbreviate LOOK by typing L. 

This gives you the option to quit playing. If you want to 
save your position, first read the instructions under "Saving 
a Game Position." You may abbreviate QUIT by typing Q. 

This ends the game and starts the game over from the 
beginning. 

This lets you pick up a game position from where you issued 
the last SAVE command. See the section on "Restoring a 
Game Position." 

This lets you save your position in a game so you can come 
back to it later. See the section on "Saving a Game 
Position." 

ZORK shows your current score with the number of moves 
you have made, and your rank. Your rank is your rating as a 
professional ZORK player and is based on the number of 
points you have and the number of moves you've made.

VERSION* 

WAIT 



This command assumes you have a printer. It commands the 
printer to begin printing a transcript of your game session. 

This command tells ZORK to show you only the name of the 
room you have entered, and no other information. It is 
briefer than BRIEF. 

Unscript stops your printer from printing. 

This command tells ZORK to show you a long description of 
the room and the objects in it whenever you enter a room. 

ZORK responds by showing you the version and serial 
number of your copy of the game. 

Tiis causes time in the game to pass. Normally, between 
moves, no time is passing as far as ZORK is concerned. You 
could leave your TRS-50. take a nap, and return to the game 
to find that nothing has changed. WAIT is used when you 
want :o find out what will happen in the game if you do 
nothing while time passes. For example, if you encounter an 
alien being, you could WAIT and see what it will do. 



How to Quit 



If you want to stop playing, and do not wish to continue this particular game 
later, type QUIT. ZORK will respond:

go blank for a moment, except for the top status line. Then the game will begin 
again. You will be West of House, with a score of and moves made. 

If yoa want to continue playing this particular game later, follow the instruc- 
tions under "Saving a Game Position." 

Saving a Game Position 

It will t-jVp you some time to play ZORK through to the end, just as it takes you 
some tim e to finish a good book. You will almost certainly not finish in one 
sitting. ZORK allows you to continue playing later without having to start over 
from the b eginning , just as you can place a bookmark in a book you are reading. 
There is a ZORK command, called SAVE, that makes a "snapshot" of your posi-' 
tion in the game. If you are a cautious or prudent player, you may want to save 
your position before you embark upon (or after you finish) any particularly tricky 
or dang erous part of the journey. Having taken a snapshot, you can go back to 
that position even though you may get lost or killed afterwards. 

Note: You must use the SCRIPT command carefully, especially when using the 
SAVE or RESTORE options. You must make sure your printer is ready to print 
(connected, on-line, enough paper, etc.) any time during the game the SCRIPT 
command is used. 

The following instructions for saving a game will require the storage diskette 
you prepared earlier. Before you attempt to save a game, you must make sure 
the program diskette is write-protected. If you have not prepared this storage 
diskette, see Appendix D (Model I) or Appendix E (Model III). 

You must be very careful when using the SAVE and RESTORE functions. Do 
not press EftfTER j until prompted. Specify the save number (Model I) or name 
(Model III) of the game, and the number of the drive you will use. with care. 
Once the SAVE and RESTORE process has started, it cannot be interrupted 
without loss of data. 

If the screen freezes, or the drives will not stop spinning after at least 90 
seconds, yoo. can press the RESET | button. This will take you to the beginning 
of the game tModel I) or to TRSDOS (Model III). You can then begin the game

Sentence Syntax 

• A ZORK sentence must contain at least a verb or a command (e.g., AGALNl. 

• Separate multiple objects of a verb by the word "and" or a comma (,).
